The invention discloses a heat conduction oil and water vapor double-medium co-production circulating fluidized bed boiler. According to a traditional circulating fluidized bed boiler, on the basis ofarranging a water actuating medium radiant heating surface, a cyclone separator, a water actuating medium convection heating surface and an air pre-heater, a heat conduction oil radiant heating surface is additionally arranged in a hearth of the circulating fluidized bed boiler, and a heat conduction oil convection heating surface is additionally arranged in a tail flue. According to the heat conduction oil and water vapor double-medium co-production circulating fluidized bed boiler, the heat conduction oil heating surfaces are additionally arranged in the circulating fluidized bed boiler, sothat heat conduction oil heating and vapor producing are conducted simultaneously, the temperature of exhaust smoke of the boiler is reduced, the thermal efficiency of the boiler is improved, and theheat load of the single boiler is improved.
